When Love Is King (1916)

Felix, the King of Wallonia, has to marry Louise, Princess of the neighboring State of Trebizond. The old Prince, her father, craves the elixir of youth, and gets drunk so often that Trebizond is in bad shape. Thus, it is up to Felix to be King of both States. But Louise has a love affair with Stepan, the heir presumptive to his throne, and Felix flees to America in disguise. By a strange twist of circumstance he takes a job as butler in the home of J.P. Morton, multi-millionaire. There he meets Marcia, Morton's daughter, and the jig is up. He loves her.
